Preface This software configuration guide provides instructions for using the Cisco command-line interface (CLI) to configure features of the following Cisco 800 series routers: • Cisco 850 Series Routers - Cisco 851 Ethernet Access Router - Cisco 857 DSL Access Router • Cisco 870 Series Routers - Cisco 871 Ethernet Access Router - Cisco 876, Cisco 877, and Cisco 878 DSL Access Routers This preface describes the intended audience, the organization of this guide, and the text and command conventions used throughout the guide. The preface includes the following topics: • Audience • Organization • Conventions • Related Documents • Obtaining Documentation and Submitting a Service Request Audience This guide is intended for network administrators whose backgrounds vary from having no or little experience in configuring routers to having a high level of experience. You can use this guide in the following situations: • You have configured the software by using the Cisco Router Web Setup tool, and you want to configure additional advanced software features by using the command-line interface (CLI). • You want to configure the software using only the CLI. Note We strongly recommend that network administrators with minimal familiarity with Cisco routers use the Cisco Router and Security Device Manager (SDM)-a web-based configuration tool that allows you to configure LAN and WAN interfaces, routing, Network Address Translation (NAT), firewalls, VPNs, and other features on your router.
